Also note the lowest on the W465 to the SW of WGT (which almost goes over BLA) is 4000 and the system would have the flight on that track on tolerances.
So from ABM WGT (4000) to BLA the system wouldnt ding until the acft was below 3700. Meanwhile ML TWR has just issued a RWY change and the controller has 4 holding at ELW to allow approach time to resequence everyone else.
Ding what ding???
